Professor Harnik is a paleontologist interested in the origin and maintenance of biodiversity in the world's oceans. Harnik received his Ph.D. from the Committee on Evolutionary Biology at the University of Chicago, after which he conducted postdoctoral research at Stanford University and the National Evolutionary Synthesis Center at Duke University. His scholarship has concentrated on the biotic and abiotic drivers of extinction and speciation over geologic time, in particular the evolutionary consequences of rarity. His current research focuses on using paleontological models to predict the response of modern marine ecosystems to current and future environmental change and integrating fossil and molecular data in macroevolutionary analyses.
